GALVANIC BATTERY.

.SPECIFICATION-formi11g part of Letters Patent No. 294,335, dated February 26, 1884.

Application filed May 11, 1883. (No model.) Patented in England September 13, 1882, No. 4,355.

To all whom it may concern:

Be it known that I, OWEN CHARLES DAL- HoUsIE Ross, a-subject of the Queen of Great Britain, residing at 50 Trafalgar Road, in the county of Surrey, England, civil engineer, have invented certain new and'useful Improvements in Galvanic Batteries, (for which I have obtained a patent in Great Britain, No. 4, 355, dated September 13, 1882,) of which the following is a specification. f

The object of my said invention is to provide an improved galvanic battery applicable to all ordinary purposes for which an electric current is required. The principal advantages are, first, that it is very economical; secondly, that it is free from the objectionable effects of polarization, and,thirdly,that it is moderately powerful. The electrodes which I employ are rods or plates of carbon and of amalgamated Zinc placed in cells and connected and arranged in the manner hereinafter mentioned, so as to form, respectively, large and suitable surfaces. When using carbon and zinc rods in circular and annular cells, I connect and arrange such rods in group's,`which are adapted to the form of the cell in which they are placed.

In VFigure 1 ofthe accompanying drawings, which ligure is a plan of a circular cell; the

annular space is occupied by a group of rods,

Y Figs. 3 and 4, which arerespectively plan and elevation of such an arrangement. There may be one row or several rows of such rods, and I combine each group of rods by means of a metal cap into one electrode in order to obtain creased quantity of electric current. A convenient method of uniting such a group is by placing the ends of the` rods together in a suitable mold, as shown inFigs. 5 and 6, and running molten lead orA other fusible metal-to a depth of about three quarters of an inch. The rods are then inverted, and the metallic cap 5o thus formed suitably groups them together` rates the two cells, as shown in plan in Fig. 7,

in which the line a b represents the separating diaphragm, and the circles c c c the rods of carbon, and z z e the rods of zinc. The diaphragm a b, placed midway or thereabout between each pair, is porous. In order to increase the surface upon which the fluid acts, a great variety of forms are available, such as are shown in Figs. 8 to 14, for example, which are drawn to an enlarged scale. I ll the cell lon that side of the diaphragm which is nearest to the carbon with a mixed liquid composed `of three parts, by weight, of hydrochloric or sulphurc acid, three partsv of water, and one part of nitrous acid. Such proportions may, however, be slightly varied. I also fill the other cell on the side of the porous diaphragm adjoining the Zinc with water slightly acidulated with from one to two per cent. of sulf phuric or hydrochloric acid. No clamps, terminals, or connecting-wires are required between the several cells of the battery so formed.

By the' employment of nitrous acid mixed withv sulphuric or hydrochloric acid and water,

as hereinbefore described, Iclaim to have discovered a new and valuablefcombination of acids which has never been hitherto used, and by means ofwhich I obtain a singularly useful battery because it is free from polarization and will maintain a current of constant strength for many hours, and is at the same time remarkably economical.

I am aware that a galvanic battery has been composed of a cell having a rubber plug from 'which is suspended a negative metal in the form of a coil of platinum around a central core, and a positive met-al in the form of zinc rods; and therefore I do not claim such features; but,

Having thus particularly described and as- IOO plates with a single cell having a diaphragm separating the carbon from'the Zine .rods or plates, substantially as shown and described.

In testimony whereof I have hereto set my hand this 25th day of April, 1882.
